Description

本発明は、道路・宅地・農地・山林などの排水路又は用水路に用いられる、一般的にＵ形側溝と呼ばれるものの変形であって、対向する側壁が、斜めに開いて立ち上がるＶ形又は湾曲的に開いて立ち上がる変形Ｕ形を含めた形状の開架側溝（以下総括的に、側溝と呼ぶ）であって、付近に生存するヘビ・カエル・カメ・ねずみ等の小動物（以下、小動物と呼ぶ）が側溝との共生を計るのに適した、工事現場での組立て施工用の工場生産による側溝部材に関するものである。   The present invention is a modification of what is commonly referred to as a U-shaped side ditch used in drainage or irrigation canals such as roads, residential land, farmland, and forests, and has a V-shaped or curved shape in which opposing side walls open obliquely and rise There are open side grooves (hereinafter collectively referred to as side grooves) including a deformed U shape that opens up and rises in the vicinity of small animals (hereinafter referred to as small animals) such as snakes, frogs, turtles, and mice that live in the vicinity. The present invention relates to a side groove member produced by a factory for assembly work at a construction site, suitable for measuring symbiosis with the side groove.

従来のＵ形側溝では、側溝内を流れる水を求めて小動物が近寄ろうとしても、壁が垂直に近く、又、壁面がコンクリートの滑らかな面となっているため、小動物が水辺に近寄ることができないケースや、一度側溝内に落下すると脱出できずに側溝内を右往左往し、最後には餓死や水死するケースが多々発生し、生態系や環境に悪影響を及ぼしていた。   In the conventional U-shaped side groove, even if a small animal tries to approach the water flowing in the side groove, the wall is almost vertical and the wall is a smooth surface of concrete, so the small animal may approach the waterside. There were many cases that could not be escaped, and once dropped into the side ditch, they could not escape and left and right in the side ditch, and eventually starved or drowned, which adversely affected the ecosystem and environment.

このような事態を受けて、最近は小動物が水辺に近寄ったり、側溝内から脱出できるような構造を備えた側溝が開発されている。   In response to this situation, recently, a gutter having a structure that allows a small animal to approach the waterside or escape from the gutter has been developed.

現在開発されている側溝をまとめると次の６種類に分けられる。
Ａ）側溝の片側壁の一部１を外側に突出させ、その空間に斜面又は階段状の通路２を設けた側溝部材。図１（Ａ）参照。 The side grooves currently being developed can be grouped into the following six types.
A) A side groove member in which a part 1 of one side wall of the side groove is protruded to the outside, and a sloped or stepped passage 2 is provided in the space. See FIG.

Ｂ）側溝の側壁の一部に開口部３を設け、その外部に斜面又は階段状の通路４を設けた側溝部材。図１（Ｂ）参照。   B) A side groove member in which an opening 3 is provided in a part of the side wall of the side groove, and a sloped or stepped passage 4 is provided outside thereof. See FIG.

Ｃ）側溝に簡易的な蓋を設置し、その蓋から下流側の底部に向かって、水に浮く板状の斜面５を設けた側溝部材。図１（Ｃ）参照。   C) A side groove member in which a simple lid is installed in the side groove, and a plate-like slope 5 that floats on water is provided from the lid toward the bottom on the downstream side. See FIG.

Ｄ）側溝内部に斜面又は階段状の通路６を設けた側溝部材。図１（Ｄ）参照。   D) A side groove member provided with a slope or stepped passage 6 inside the side groove. Refer to FIG.

Ｅ）側溝の側壁の一部に開口部７を設け、その外部は土砂の埋め戻しを行わず解放的な空間８を確保した側溝部材。図１（Ｅ）参照。   E) A side groove member in which an opening 7 is provided in a part of the side wall of the side groove, and the outside is not backfilled with earth and sand and a releasable space 8 is secured. Refer to FIG.

Ｆ）側溝内部の底部に山状の通路９を設けた側溝部材。図１（Ｆ）参照。   F) A side groove member provided with a mountain-shaped passage 9 at the bottom inside the side groove. Refer to FIG.

側溝は道路・宅地・農地・山林などの雨水排水路又は農業用水路にも用いられる構造物である。但し、工場廃水路に用いられても良いので、雨水排水路用に限定される訳ではない。   The gutter is a structure that is also used for rainwater drainage channels such as roads, residential land, farmland, and forests, or agricultural waterways. However, since it may be used for a factory wastewater channel, it is not limited to a rainwater drainage channel.

従来は、内部の水を流したり送ったりすることに重点が置かれ、小動物が水辺に近寄ることや、誤って落下した場合の配慮はあまりなかった。   Conventionally, emphasis was placed on the flow and sending of internal water, and there was little consideration when a small animal approached the waterside or accidentally dropped.

以上のことを考慮して、現在開発されている側溝の問題点をまとめると次の６種類に分けられる。   Considering the above, the problems of the currently developed gutters can be summarized into the following six types.

Ａ）側溝の片側壁の一部を外部に突出させ、その空間に斜面又は階段状の通路部分を設けた場合は、側溝が用地境界として使用されることがほとんどであるため、外部の一部に大きな凸部が有ることは実用化において困難なところがある。   A) When a part of one side wall of the gutter is protruded to the outside and a sloped or stepped passage portion is provided in the space, the gutter is mostly used as a site boundary. It is difficult in practical use to have a large convex portion.

さらに、側溝の一方向に斜面又は階段状の通路が設けられるため、小動物の生息域が分断される。これを避けるに、通路部分を数本おきに互い違いに設置した場合は、側溝による空間が凹凸状になるため、設置後の景観が見苦しくなる。   Furthermore, since a slope or stepped passage is provided in one direction of the side groove, the habitat of small animals is divided. In order to avoid this, when several passage portions are installed alternately, the space by the side grooves becomes uneven, and the landscape after installation becomes unsightly.

又、通路部分が側溝の長さ方向の一区間に限定されるため、その区間で往来できない場合は、次の通路を探さなければならず、到達できない場合は死に至る場合もありうる。   In addition, since the passage portion is limited to one section in the length direction of the side groove, if it is not possible to travel in that section, the next passage must be searched, and if it cannot be reached, death may occur.

Ｂ）側溝の側壁の一部に開口部を設け、その外部に斜面又は階段状の通路部分を設けた場合もＡ）と同様に側溝外部の一部に大きな凸部ができるため用地境界の問題から実用化において困難なところがある。   B) Even when an opening is provided in a part of the side wall of the gutter and a sloped or stepped passage portion is provided outside the same, a large convex part is formed in a part outside the gutter as in A). Therefore, there are some difficulties in practical application.

加えて、小動物の生息域が分断され、又、通路部分が限定されるため次の通路を探さなければならない。   In addition, since the habitat of small animals is divided and the passage section is limited, the next passage must be searched.

さらに、開口部の大きさによっては、側溝の強度低下をまねき、付近が危険にさらされることになる。   Furthermore, depending on the size of the opening, the strength of the side groove is reduced, and the vicinity is exposed to danger.

Ｃ）側溝に簡易的な蓋を設置し、その蓋から下流側の底部に向かって板状の斜面を設けた場合は、板状の斜面が流水の浮力により上下し、落ち葉等の浮流物を通過させるような構造となっているため、おのずから、通路の方向が限定される。   C) When a simple lid is installed in the gutter and a plate-like slope is provided from the lid toward the bottom on the downstream side, the plate-like slope rises and falls due to the buoyancy of running water, and floats such as fallen leaves are removed. Since the structure allows the passage, the direction of the passage is naturally limited.

Ｄ）側溝内部に斜面又は階段状の通路部分を設けた場合は、あらかじめ、その地域を対象とした流量計算により求められた側溝の必要通水断面を阻害するため、実用化において困難なところがある。   D) When a sloped or stepped passage portion is provided inside the gutter, there is a difficulty in practical use because it obstructs the necessary water cross section of the gutter obtained by calculating the flow rate for the area in advance. .

Ｅ）側溝の側壁の一部に開口部を設け、その外部は土砂の埋め戻しを行わず解放的な空間を確保した場合は、側溝の内部を水が流れない場合は問題ないが、水が流れる場合は漏水等の問題を生じ、側溝としての本来の機能が失われる。   E) When an opening is provided in a part of the side wall of the gutter and the outside is not backfilled with earth and sand and a releasable space is secured, there is no problem if water does not flow inside the gutter. When flowing, problems such as water leakage occur, and the original function as a side groove is lost.

又、外部の土砂の埋め戻しを行わないような場所は、山間部などの一部に限定される。   Moreover, the place where the external earth and sand are not backfilled is limited to a part of a mountainous area.

Ｆ）側溝内部の底部に山状の通路を設けた場合は、あらかじめ、その地域を対象とした流量計算により求められた側溝の必要通水断面積を減少させるため、実用化において困難なところがある。   F) When a mountain-shaped passage is provided at the bottom inside the gutter, there is a difficulty in practical use because the necessary cross-sectional area of the gutter obtained by the flow calculation for the area is reduced in advance. .

以上の問題点を解決するために考えた手段を下記に示す。
Ａ）側溝は用地境界に設置される場合がほとんどであるため、側溝の外部に凸部等を設けないものとする。 The means considered to solve the above problems are shown below.
A) Since the gutter is mostly installed at the land boundary, no convex part or the like is provided outside the gutter.

Ｂ）側溝は用地境界に設置される場合がほとんどであるため、側溝の外部に付属の構造物を設けないものとする。   B) Since the gutter is mostly installed at the land boundary, the attached structure is not provided outside the gutter.

Ｃ）通路用斜面又は階段の位置は限定しないものとする。   C) The position of the slope for the passage or the stairs shall not be limited.

Ｄ）通路用斜面又は階段の方向は限定しないものとする。   D) The direction of the slope for the passage or the stairs shall not be limited.

Ｅ）側溝の側壁に機能を低下させるような開口部を設けないこと。   E) Do not provide an opening that lowers the function on the side wall of the side groove.

Ｆ）その地域の流量計算で決定された側溝の通水量を減少させないものとする。   F) The amount of water flow through the gutter determined by the local flow rate calculation shall not be reduced.

上記のＡ）からＦ）を解決するために、この発明では側溝の側壁内面に階段状の昇降段を設け、そこから小動物が自由に側溝内外へ往来できるような構造とした。   In order to solve the above A) to F), in the present invention, a stepped elevating step is provided on the inner surface of the side wall of the side groove, from which a small animal can freely move in and out of the side groove.

本発明の側溝を用いることによる効果を下記に箇条書きする。
Ａ）側壁の外部に余分な構造物や突出物を必要としないために、用地境界が明確になる。
Ｂ）側溝を施工する場合に方向等を考える必要が無い。
Ｃ）側壁に開口部等を設けないため、側溝としての強度低下が無い。
Ｄ）小動物は、いかなる場所からでも、外部と側溝内を往来することができる。
Ｅ）本発明の側溝では本来の流水量を減少させない。 The effects of using the side grooves of the present invention are listed below.
A) Since no extra structure or protrusion is required outside the side wall, the land boundary becomes clear.
B) There is no need to consider the direction etc. when constructing gutters.
C) Since no opening or the like is provided on the side wall, there is no reduction in strength as a side groove.
D) Small animals can come and go from outside to inside the gutter from any location.
E) The flow rate of the present invention does not reduce the original flow rate.

Yes.

図２（Ｅ）に示す斜視図は、側壁内面の状態を表したもので、昇降段２５の断面形状をわかり易く示したものである。昇降段２５は、複数の踏面２５ａ及び蹴上げ面２５ｂを有する。   The perspective view shown in FIG. 2 (E) shows the state of the inner surface of the side wall, and shows the sectional shape of the elevating stage 25 in an easy-to-understand manner. The elevating stage 25 has a plurality of treads 25a and kick-up surfaces 25b.

ここで、昇降段２５は、側溝部材２１の長さ方向に対して平行に設けられているが、必ずしも平行である必要はない。   Here, although the raising / lowering stage 25 is provided in parallel with the length direction of the gutter member 21, it does not necessarily need to be parallel.

図３は、本発明の側溝の第２実施例を示したもので、（Ａ）は平面図、 （Ｂ）は側溝を長さ方向に対して直角にａ−ａ線で切断して示す断面図であって、水平方向の底版３４と左右の上下方向に伸びた左側壁３２と右側壁３３とから構成され、下部の内幅に対して上部の内幅の方が広くなっており、側壁内面には階段状の昇降段３５が下部から上部まで設けられている。この実施例では各段の昇降段３５の断面形状は同一ではなく、大小を任意に配置している。   3A and 3B show a second embodiment of the side groove of the present invention, in which FIG. 3A is a plan view, and FIG. 3B is a cross-sectional view showing the side groove cut along aa line at right angles to the length direction. It is composed of a horizontal bottom slab 34, left and right side walls 32 and right side wall 33 extending in the vertical direction on the left and right sides, and the upper inner width is wider than the lower inner width. On the inner surface, a step-like elevating stage 35 is provided from the lower part to the upper part. In this embodiment, the cross-sectional shapes of the raising and lowering stages 35 are not the same, and the sizes are arbitrarily arranged.

斜視図（Ｅ）は、左側壁内面の状態を表したもので、昇降段３５の断面形状をわかり易くしたものである。３５ａは昇降段の踏面を示し、３５ｂは商工段の蹴上げ面を示す。   The perspective view (E) shows the state of the inner surface of the left side wall, and makes the cross-sectional shape of the elevating stage 35 easy to understand. 35a shows the tread surface of the raising / lowering stage, and 35b shows the kicking surface of the commercial stage.

この実施例では、昇降段は側溝部材３１の長さ方向と平行に設けられているが、必ずしも平行である必要はない。   In this embodiment, the elevating stage is provided in parallel with the length direction of the side groove member 31, but it is not necessarily required to be parallel.

図４は、本発明の側溝部材の第３実施例を示したもので、隣接する区間Ｌ１、Ｌ２の昇降段の断面形状ばかりか、夫々の対向する側面の昇降段４５の断面形状も相違した実施形態を示す。（Ａ）は側溝部材４１の長さ方向をＬ１区間とＬ２区間に分けた場合の平面図であり、ａ−ａ線で切断して示す断面図（Ｂ）はＬ１区間を長さ方向に対して直角に切断した断面を示し、水平方向の底版４４と左右の上下方向に立ち上がる左側壁４２と右側壁４３とから構成され、下部の内幅に対して上部の内幅の方が広くなっており、側壁内面には踏面４５ａ及び蹴上げ面４５ｂを有する階段状の昇降段４５が下部から上部まで設けられている。   FIG. 4 shows a third embodiment of the side groove member according to the present invention, and not only the sectional shape of the raising and lowering steps of the adjacent sections L1 and L2, but also the sectional shape of the raising and lowering steps 45 on the opposite side surfaces are different. An embodiment is shown. (A) is a top view at the time of dividing the length direction of the side groove member 41 into L1 area and L2 area, and sectional drawing (B) cut | disconnected and shown by the aa line shows L1 area with respect to a length direction The cross section is cut at a right angle, and is composed of a horizontal bottom plate 44, a left side wall 42 and a right side wall 43 that rise in the left and right vertical directions, and the inner width of the upper portion is wider than the inner width of the lower portion. In addition, a step-like elevating step 45 having a tread surface 45a and a kick-up surface 45b is provided on the inner surface of the side wall from the lower part to the upper part.

この実施例では、向き合った左側壁４２と右側壁４３の昇降段４５の形状が相違するばかりでなく、同一側壁に属する各段の昇降段４５の断面形状も同一ではない点に注意されたい。この事実は、同図のｂ−ｂ線で切断して示す断面図（Ｃ）を参照すると、Ｌ２区間の左側壁４２と右側壁４３の各段の昇降段４５の断面形状は同一ではないことからも明らかである。   In this embodiment, it should be noted that not only the shapes of the raising and lowering stages 45 of the left side wall 42 and the right side wall 43 facing each other are different, but also the sectional shapes of the raising and lowering stages 45 of each stage belonging to the same side wall are not the same. As for this fact, referring to the sectional view (C) shown by cutting along the line bb in the same figure, the sectional shape of the elevating stage 45 of each stage of the left side wall 42 and the right side wall 43 in the L2 section is not the same. It is clear from

左側壁内面図（Ｄ）は、左側壁を内面から見た図で、ａ−ａ線断面図（Ｂ）の左側半分に示された左側壁に係る異なった任意高さのＬ１区間の昇降段と、ｂ−ｂ線断面図（Ｃ）の右側半分に示される異なった任意の高さのＬ２区間の昇降段とが設けられている。   The left side wall inner view (D) is a view of the left side wall as viewed from the inner side, and is a lifting stage of L1 section of different arbitrary heights related to the left side wall shown in the left half of the cross-sectional view along line aa (B). And an elevating stage of the L2 section of different arbitrary height shown in the right half of the cross-sectional view (C) along the line bb.

右側壁内面図（Ｅ）は、右側壁４３を内面から見た図で、ａ−ａ線断面図（Ｂ）の右半分に示された右側壁に係る異なった任意の高さのＬ１区間の昇降段と、ｂ−ｂ線断面図（Ｃ）右半分に示される異なった任意の高さのＬ２昇降段が設けられている。   The right side wall inner view (E) is a view of the right side wall 43 as seen from the inner side, and shows L1 sections of different arbitrary heights related to the right side wall shown in the right half of the cross-sectional view along the line aa. An elevating stage and an L2 elevating stage of different arbitrary height shown in the right half of the bb line cross-sectional view (C) are provided.

斜視図（Ｆ）は、右側壁４３の内面の状態を表したもので、昇降段４５の断面形状をわかり易くしたものである。   The perspective view (F) shows the state of the inner surface of the right side wall 43 and makes the sectional shape of the elevating stage 45 easy to understand.

側溝部材の長さ方向を数ヶ所の区間に分ける方法において、その分け方は特定しないので、左側壁４２と右側壁４３で区間数を異ならせても良く、又、側壁下部と側壁上部の区間の長さを異ならせても問題ない。   In the method of dividing the length direction of the side groove member into several sections, the way of dividing is not specified, so the number of sections may be different between the left side wall 42 and the right side wall 43, and the lower side wall part and the upper side wall part There is no problem even if the length of is different.

ここで、昇降段４５は側溝部材の長さ方向と平行に設けた例が図示されているが、必ずしも平行である必要はない。   Here, although the example in which the elevating stage 45 is provided in parallel with the length direction of the side groove member is illustrated, it is not necessarily required to be parallel.

図５は、本発明の側溝部材の第４実施例を示した図である。同図の平面図（Ａ）は、側溝を上部から見た図で、Ｌ１区間はａ−ａ線断面図（Ｂ）に示される比較的大幅の昇降段５５、Ｌ２区間はｂ−ｂ線断面図（Ｃ）に示される半分幅の２本の傾斜通路５８、Ｌ３区間はｃ−ｃ線断面図（Ｄ）に示される比較的大幅の昇降段５５が設けられている。   FIG. 5 is a view showing a fourth embodiment of the gutter member of the present invention. The plan view (A) of the figure is a view of the side groove as viewed from the top, and the L1 section is a relatively large lifting stage 55 shown in the aa sectional view (B), and the L2 section is a bb sectional view. In the two inclined passages 58 and L3 having a half width shown in FIG. (C), a comparatively large lifting stage 55 shown in the sectional view (c) taken along the line cc is provided.

側溝部材の長さ方向をＬ１区間・Ｌ２区間・Ｌ３区間に分けた場合、ａ−ａ線断面図（Ｂ）はＬ１区間を長さ方向に対して直角に切断した断面を表す図で、水平方向の底版５４と上下方向の左側壁５２と右側壁５３とから構成され、下部の内幅に対して上部の内幅のほうが広くなっており、側壁内面には階段状の昇降段５５が下部から上部まで設けられている。ここで各段の昇降段の断面形状は同一に限らず、大小を任意に配置しても良い。   When the length direction of the side groove member is divided into the L1 section, the L2 section, and the L3 section, the cross-sectional view along line aa (B) is a diagram showing a cross section of the L1 section cut at right angles to the length direction. A bottom plate 54 in the vertical direction, a left side wall 52 in the vertical direction, and a right side wall 53. The inner width of the upper part is wider than the inner width of the lower part. From the top to the top. Here, the sectional shape of the raising and lowering steps is not limited to the same, and may be arbitrarily arranged.

ｂ−ｂ線断面図（Ｃ）はＬ２区間を長さ方向に対して直角に切断した断面を表す図で、水平方向の底版５４と左右の上下方向の側壁から構成され、下部の内幅に対して上部の内幅の方が広くなっており、側壁内面には階段状の傾斜通路５８が下部から上部まで設けられている。   BB line sectional view (C) is a view showing a section obtained by cutting the L2 section at a right angle with respect to the length direction, and is composed of a horizontal bottom plate 54 and left and right side walls in the vertical direction.

ｃ−ｃ線断面図（Ｄ）はＬ３区間を長さ方向に対して直角に切断した断面を表す図で、水平方向の底版５４と、上下方向に立ち上がる左側壁５２と右側壁５３とから構成され、下部の内幅に対して上部の内幅のほうが広くなっており、側壁内面には階段状の昇降段５５が下部から上部まで設けられている。ここで各段の断面形状は同一に限らず、大小を任意に配置しても良い。   The cc line sectional view (D) is a diagram showing a section obtained by cutting the L3 section at a right angle to the length direction, and is composed of a bottom plate 54 in the horizontal direction, a left side wall 52 and a right side wall 53 rising up and down. The upper inner width is wider than the lower inner width, and a stepped lifting stage 55 is provided on the inner surface of the side wall from the lower part to the upper part. Here, the cross-sectional shape of each step is not limited to the same, and may be arbitrarily arranged.

左側壁内面図（Ｅ）は、左側壁５２を内面から見た図で、Ｌ１区間はａ−ａ線断面図（Ｂ）に示される昇降段５５、Ｌ２区間はｂ−ｂ線断面図（Ｃ）に示される傾斜通路５８、Ｌ３区間はｃ−ｃ断面図（Ｄ）に示される昇降段５５が設けられている。   The left side wall inner view (E) is a view of the left side wall 52 as viewed from the inner side, and the L1 section is the lifting stage 55 shown in the aa line sectional view (B), and the L2 section is the bb line sectional view (C). In the inclined passage 58 and the L3 section shown in (), an elevating stage 55 shown in the cc cross-sectional view (D) is provided.

右側壁内面図（Ｆ）は、右側壁５３を内面から見た図で、Ｌ１区間はａ−ａ線断面図（Ｂ）に示される昇降段、Ｌ２区間はｂ−ｂ線断面図（Ｃ）に示される傾斜通路５８、Ｌ３区間はｃ−ｃ線断面図（Ｄ）に示される昇降段が設けられている。   The right side wall inner surface view (F) is a view of the right side wall 53 as viewed from the inner surface, the L1 section is the lifting stage shown in the aa sectional view (B), and the L2 section is the bb sectional view (C). In the inclined passage 58 and the L3 section shown in FIG. 4, the elevating stage shown in the sectional view (c) taken along the line cc is provided.

斜視図（Ｇ）は、側壁内面の状態を表したもので、請求項５の記載に係る「つづら折れ連絡路」の構成を、分かり易く例示している。   The perspective view (G) shows the state of the inner surface of the side wall, and illustrates the configuration of the “split-fold communication path” according to claim 5 in an easy-to-understand manner.

Ｌ２区間に例示した傾斜通路は、隣接するＬ１区間とＬ３区間を結んで、段から段への小動物の移動又は往来を容易化するための、バリアフリー対応例として配置した。なお、図５に示す実施例においては、Ｌ１区間及びＬ３区間の昇降段の断面形状を夫々異ならせて例示しているが、Ｌ１区間及びＬ３区間の昇降段の形状を同一又は段違いの形状にすることにより他の連絡路構成、例えば右上がりの傾斜通路のみを設けた「Ｚ形連絡路」の構成にしても良い。   The inclined passage illustrated in the L2 section is arranged as a barrier-free correspondence example for facilitating the movement or transportation of small animals from one stage to another by connecting the adjacent L1 and L3 sections. In the embodiment shown in FIG. 5, the sectional shapes of the elevating steps in the L1 section and the L3 section are illustrated differently, but the shapes of the elevating stages in the L1 section and the L3 section are the same or different shapes. By doing so, another communication path configuration, for example, a “Z-shaped communication path” configuration in which only an upwardly inclined path is provided may be used.

側溝部材の長さ方向を何ヶ所の区間に分けるかは特定しないので、左側壁と右側壁で区間数が異なっても良く、又、側壁下部と側壁上部の区間の長さが異なっても問題ない。さらに、どの区間に設けるかに特定せず、又例示の昇降段の形状とは異なっても差し支えない。   It is not specified how many sections the length direction of the side groove member is divided, so the number of sections may be different on the left side wall and the right side wall, and the length of the sections on the lower side wall and upper side wall may be different. Absent. Further, it is not specified in which section, and it may be different from the shape of the illustrated elevating stage.

ここで、昇降段は側溝部材の長さ方向と平行に設けられているが、必ずしも平行である必要は無い。   Here, although the raising / lowering stage is provided in parallel with the length direction of the gutter member, it does not necessarily need to be parallel.

図６は、本発明の側溝部材の第５実施例を示したものであって、図４に示す第３実施例の変形に相当する。即ち、変形前の図４に示す側溝部材の実施態様を振り返って見ると、左側の区間Ｌ２の昇降段４５の段毎に相違する各蹴上げ面４５ｂの高さは、区間Ｌ２内では夫々一定の高さを維持して各踏面４５ａは水平である。   FIG. 6 shows a fifth embodiment of the gutter member of the present invention, and corresponds to a modification of the third embodiment shown in FIG. That is, looking back at the embodiment of the side groove member shown in FIG. 4 before the deformation, the height of each kicking surface 45b that is different for each step of the lifting step 45 of the left section L2 is constant in the section L2. The treads 45a are horizontal while maintaining the height.

同様にその右側の区間Ｌ１の昇降段４５の段毎に相違する各蹴上げ面４５ｂの高さは、区間Ｌ２内では夫々一定の高さを維持して各踏面４５ａは水平である。そして、両区間の中央境界線において高さが突然に変更されている。この状態は図４（Ｆ）の斜視図に明示されている。   Similarly, the height of each kicking surface 45b, which is different for each of the lifting and lowering stages 45 in the right section L1, maintains a constant height in the section L2, and each tread 45a is horizontal. And the height is suddenly changed in the center boundary line of both sections. This state is clearly shown in the perspective view of FIG.

これに対して、図６においてはその斜視図（Ｆ）に見られるとおり、各側溝部材の左端にある昇降段の蹴上げ面６５ｂから各側溝部材の右端にある高さの異なる蹴上げ面６５ｂへと連続されて、徐々に高さが変わり、向って左右方向に斜面をなす踏み面６５ａを形成している。   On the other hand, in FIG. 6, as seen in the perspective view (F), from the lifting surface 65b of the lifting stage at the left end of each side groove member to the lifting surface 65b of the different height at the right end of each side groove member. Continuously, the height gradually changes, and a tread surface 65a that forms a slope in the left-right direction is formed.

ここで、例えば図６（Ｆ）の向って右端の昇降段の最下段の蹴上げ面６５ｂ１を見ると、ここは相対的に低く上り易くなっている。 但し右端で直登を試みると、右端の下から二番目の蹴上げ面６５ｂ２の高さが相対的に高くなっているので、上りにくい。この場合は一番下の昇降段の踏面６５ａ１から直登せずに、踏み面６５ａ１の上を伝って左へ進むと、相対的に低い第二番目の蹴上げ面６５ｂ３の足下に到達する。   Here, for example, when viewing the lowermost kick-up surface 65b1 of the lift stage at the right end in the direction of FIG. 6 (F), it is relatively easy to rise. However, if a straight climb is attempted at the right end, the second kick-up surface 65b2 from the bottom of the right end is relatively high, so that it is difficult to climb. In this case, without going straight up from the tread surface 65a1 of the lowest elevating step, when traveling to the left over the tread surface 65a1, the foot reaches the foot of the relatively low second kick-up surface 65b3.

その蹴上げ面６５ｂ３を昇ってから踏面６５ａ２上を伝って右に進むと、下から二番目の昇降段の踏面６５ａ２の右端の上に難なく到達することができる。 この要領で、上り易いところを選んで昇ることにより左側壁６２の一番上の踏面に到達でき、つまり、脱出に成功することができる。   After going up the kicking surface 65b3 and traveling right on the tread 65a2, it is possible to reach the right end of the tread 65a2 of the second elevating step from the bottom without difficulty. In this way, it is possible to reach the uppermost tread surface of the left side wall 62 by selecting a place where it is easy to ascend, that is, to escape successfully.

図６のａ−ａ線断面図（Ｂ）及びｂ−ｂ線断面図（Ｃ）を参照すると、下部の内幅に対して上部の内幅の方が広くなっており、側壁内面には階段状の昇降段が下部から上部まで設けられているが、各段の昇降段６５の断面形状は同一ではなく、大小を任意に配置されていることが分かる。   6A and 6B, the upper inner width is wider than the lower inner width, and a staircase is formed on the inner surface of the side wall. However, it is understood that the cross-sectional shape of the lift stage 65 is not the same, and the size is arbitrarily arranged.

図７は、側溝設置場所における特殊事情に応じて、優先的に脱出させようとする小動物の種類や大きさに応じて、選択されるべき昇降段６５の断面形状を実線ａ−ｂ−ｃで結んで例示した図である。   FIG. 7 shows the cross-sectional shape of the elevating stage 65 to be selected by solid lines abc according to the kind and size of the small animal to be preferentially escaped according to the special circumstances at the side groove installation location. It is the figure which tied and illustrated.

同図の（Ａ）は、最も標準的な昇降段の断面形状を示す図であって、側溝踏面７５ａを水平線に対して平行（θ１＝１８０°）に、蹴上げ面７５ｂを垂直（θ２＝２７０°）に形成した例を示す。   (A) of the figure is a diagram showing the cross-sectional shape of the most standard lifting stage, in which the side groove tread surface 75a is parallel to the horizontal line (θ1 = 180 °) and the kicking surface 75b is vertical (θ2 = 270). °) shows an example.

同図の（Ｂ）は、踏面７５ａの奥を低くして踏面から滑り落ち難くした（１８０°＜θ１＜２７０°）例を示す。   FIG. 5B shows an example in which the depth of the tread 75a is lowered to make it difficult to slide off the tread (180 ° <θ1 <270 °).

同図の（Ｃ）は、踏面７５ａの奥を高くすることにより、例えば蛇のような体型が細長く鱗で覆われ手足がない動物の場合に、何段にも亘って攀じ登り易い昇降段の断面形状（９０°＜θ１＜１８０°）の例を示す。   (C) in the figure shows an elevating step that can be easily climbed over many steps by raising the depth of the tread 75a so that, for example, a snake-like body is elongated and covered with scales and has no limbs. An example of a cross-sectional shape (90 ° <θ1 <180 °) is shown.

同図の（Ｄ）は、蹴上げ面７５ｂをオーバハングにして踏面７５ａを広くした（１８０°＜θ２＜２７０°）例を示す。   FIG. 4D shows an example in which the kicking surface 75b is overhanged to widen the tread surface 75a (180 ° <θ2 <270 °).

同図の（Ｅ）は、蹴上げ面７５ｂの傾斜を多少緩くして垂直登攀を回避できる形態として、例えば蛇のような体型が細長く鱗で覆われ手足がない動物の場合に何段にも亘って攀じ登り易い昇降段の断面形状（２７０°＜θ２＜３６０°）の例を示す。   (E) of the figure shows a form in which the inclination of the kick-up surface 75b is slightly relaxed to avoid vertical climbing, for example, in the case of an animal with a slender body shape that is covered with scales and has no limbs. An example of the cross-sectional shape (270 ° <θ2 <360 °) of the elevating stage that is easy to climb is shown.

同図の（Ｆ）は、踏面７５ａの奥を低くし、且つ蹴上げ面７５ｂをオーバーハングにした（θ１＜θ２，１８０°＜θ１＜２７０°，１８０°＜θ２＜２７０°）例を示す。このようなオーバーハング断面形状の昇降段で側壁内面を構成した場合には、側壁内面をＶ形に斜め直線状に立ち上げる必要はなく、途中から垂直に近い形で立ち上げて、Ｕ形に構成しても良い。   FIG. 5F shows an example in which the depth of the tread surface 75a is lowered and the kick-up surface 75b is overhanged (θ1 <θ2, 180 ° <θ1 <270 °, 180 ° <θ2 <270 °). In the case where the side wall inner surface is configured by such an elevating stage having an overhang cross-sectional shape, it is not necessary to raise the side wall inner surface in an oblique linear shape to a V shape. It may be configured.

同図の（Ｇ）は、（１８０°＜θ１＜２７０°，２７０°＜θ２＜３６０°）にした例を示す。   (G) of the figure shows an example in which (180 ° <θ1 <270 °, 270 ° <θ2 <360 °) is set.

同図の（Ｈ）は、（９０°＜θ１＜１８０°，１８０°＜θ２＜２７０°）にした例を示す。   (H) of the figure shows an example in which (90 ° <θ1 <180 °, 180 ° <θ2 <270 °).

同図の（Ｉ）も又、前述の（Ｃ）や（Ｅ）と同様に、例えば蛇のような体型が細長く鱗で覆われ手足がない動物の場合に何段にも亘って攀じ登り易い昇降段の断面形状（９０°＜θ１＜１８０°，２７０°＜θ２＜３６０°）にした例を示す。   Similarly to (C) and (E) above, (I) in the figure also climbs in many steps in the case of an animal with a slender body shape that is covered with scales and has no limbs. An example in which the cross-sectional shape of an easy lifting stage (90 ° <θ1 <180 °, 270 ° <θ2 <360 °) is shown.

上記に示した全ての実施例において、 斜めに開いて立ち上がる対向する側壁が、直線的に立ち上がる例を示したが、 この例に限定するものではなく、 昇降段の高さ、及び／又は踏みしろの幅（広さ）の変化に対応して、非直線的に立ち上がるようにしても良い。   In all the embodiments described above, the example in which the opposing side walls that rise obliquely and rise up linearly has been shown. However, the present invention is not limited to this example, and is not limited to this example. In response to a change in the width (width) of the image, it may stand up non-linearly.

流水量が、常時比較的多く、底板付近の昇降段は不要であると考えられる場所に用いる開架側溝路用のものに関しては、 昇降段を側溝の比較的上部に限定して設けることによって、製造コストを低減しても良い。   For open side gutters used in places where the amount of water flow is relatively large at all times and where the elevating stage near the bottom plate is not necessary, it is manufactured by limiting the elevating stage to the relatively upper part of the side groove. Cost may be reduced.
